Description

Technical Field

[0001] The present disclosure relates to a unit module of a fuel cell humidifier and a fuel cell humidifier including the same, and more particularly, to a unit module of a fuel cell humidifier and a fuel cell humidifier including the same, wherein a unit module including a plurality of cartridges is manufactured, and a fuel cell humidifier is manufactured using the unit module, such that the fuel cell humidifier may be manufactured in various forms.

Background Art

[0002] A fuel cell is a power-generating battery that produces electricity by combining hydrogen and oxygen. Unlike typical chemical cells such as batteries or accumulators, fuel cells may continuously produce electricity as long as hydrogen and oxygen are supplied, and since there is no heat loss, they have the advantage of efficiency about twice that of internal combustion engines.

[0003] A fuel cell system includes a stack, which is an electricity-generating assembly of unit fuel cells each composed of a cathode and an anode, an air supply device for supplying air to the cathode of the fuel cells, and a hydrogen supply device for supplying hydrogen to the anode of the fuel cells.

[0004] In order for an ion-exchange membrane of a membrane-electrode assembly (MEA) of a polymer fuel cell of the fuel cell system to function smoothly, an appropriate amount of moisture is required, and for this purpose, a humidifier is provided in the air supply device of the fuel cell system to humidify the air supplied to the fuel cells.

[0005] The humidifier uses the moisture in the high-temperature, humid exhaust gas discharged from the cathode of the fuel cell, to humidify the dry gas supplied through an air compressor of the air supply device, and supplies the humidified air to the cathode of the fuel cells.

[0006] A fuel cell humidifier uses a membrane humidification method. A membrane humidifier performs membrane humidification through a method of gas-to-gas moisture exchange between the high-temperature, humid exhaust gas discharged from the cathode of the fuel cells, and the dry gas supplied through the air compressor.

[0007] The fuel cell humidifier may be provided with a cartridge in which a humidification membrane formed of a hollow fiber membrane is arranged. Dry gas passes through the hollow fiber membrane through one side and the other side of the cartridge, and an opening (window) that is open to the outside is provided on a side surface of the cartridge.

[0008] Exhaust gas flows into the cartridge through the opening of the cartridge, and the exhaust gas flowing into the cartridge exchanges moisture with the dry gas passing through the hollow fiber membrane.

[0009] However, in the related art, fuel cell humidifiers using a cartridge have the following problems. A housing of a fuel cell humidifier may be provided with a plurality of cartridges, and the number of cartridges provided in the housing may change depending on the amount of humidified air supplied to the fuel cells.

[0010] For fuel cell humidifiers using a cartridges, there is a problem in that a separate housing has to be manufactured according to the number of cartridges installed inside the housing. In addition, fuel cell humidifiers in the art have the problem of excessive manufacturing costs as they must be manufactured in various ways depending on the amount of humidified air supplied to the fuel cell.

[0011] In addition, in the art, fuel cell humidifiers using cartridges have the problem that it is difficult to replace a cartridge when the humidification membrane inside the cartridge is damaged. The humidification membrane inside the cartridge may be damaged by use of a fuel cell humidifier, in which case the cartridge has to be replaced.

[0012] However, in the art, fuel cell humidifiers using cartridges have a problem in that it is difficult to replace cartridges with damaged humidification membranes because the cartridges and housing are formed as one piece.

Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0037] Referring to FIG. 1, a unit module 100 of a fuel cell humidifier according to an embodiment of the present disclosure includes a module housing 110 and a cartridge 120.

[0038] The module housing 110 is formed in a hexahedral shape and has a first opening 117 on an upper surface 113, lower surface 114, front surface 115, and rear surface 116.
